Jeff Raider is the cofounder and co-CEO of the razor company Harry’s, an online subscription service that sends high-end razors to customers at a low cost. The company raised $112 million earlier this year to move the brand beyond shaving to include all kinds of men’s grooming products. Before cofounding Harry’s, Raider also pioneered the eyewear company Warby Parker, which became successful using a similar model of online retail. Raider’s focus is on building brands he’d like to use in his own life. But before he became an entrepreneur, he was at Wharton Business School on a typical path to finance.
